just found out a friend and his wife DM AD&D group basically a war of the lance setting they told me of how a player was playing a lawful good knight and caused them to lose a town the need to help with their navy seem the to whose main export was pitchs pits used for waterproofing ship hulls and other uses from a few local tar pit the knight had a plan to trap and kill a huge red dragon using the tar pits
( someone watched beastmaster a few too many times)lol anyway the traped worked somewhat I was told it did trap it for a short time and did gum up the wing too but the DM( had a surprise red dragon or any dragon was immune to the type of damage of its breath weapon so fire and heat had no effect on it )so to escape it simply lite the pits on fire and escaped now very upset at the town it walks thru the town fling globs of flaming pitch on building, homes, ships in the river and, people burning the town down the pits are still burning and slow the people trying to fight this war down more

see this is why I play a thief someone says dragon I move on unless someone says the dragons away or is dead then I look for it hoard

yes I was told the knight did survive i think the dragon was having too much fun burning their town
